Two-thirds of the world’s population consumes tea.1 The three major types of tea are black, oolong, and green. These types of tea differ in how they are produced and if they are fermented. Black tea is produced by oxidizing the leaves. This method intensifies the flavor and turns the leaves a dark brown color. Oolong tea is made by partially exposing the leaves to air. It is considered to be an intermediate between black and green tea in terms of flavor and caffeine levels. Green tea is the only type that is non-fermented. It is produced using young tea leaves and sold for consumption after withering.2
For many centuries, green tea has been used in ancient Chinese medicine as a way to treat various maladies from hyperlipidemia to Alzheimer

They were asked to refrain from any use of green tea products amongst various other things 24 hours before each study day. The study days were once a week for a month. The participants did not consume pure green tea extract, instead they were given a soft drink, Rivella, that contained 0.05% green tea extract. Since the green tea extract was in a soft drink, there were other ingredients present, such as milk whey, lactic acid, calcium cyclamate, acesulfame K, sodium, potassium, magnesium, calcium, and chloride. As a control condition, other participants were given the same soft drink without the green tea extract. The participants swallowed a feeding tube for application of the test solutions so they would not be able to taste the differences between the two drinks. After it was administered, the participants were scanned four times and results were …show more content…
The researchers reported that green tea extract increased the connectivity from the right superior parietal lobule to the middle frontal gyrus. Due to this increased connectivity, there was an increased positive effect on task performance which suggests a positive effect of green tea consumption on cognitive functioning. In the conclusion section, the researchers suggest that this study provides a promising tool to assess the efficacy of green tea extract for the treatment of psychiatric disorders such as
The subject was then asked to perform the same steps as last week in addition to getting their blood lactate taken before activity begins and again at every increase in incline. These processes were performed the following week as well, but the test subject was given a concoction that contained 250 mg of caffeine. This study was a double blind study in which the instructors, nor the subjects knew when the test subject was given caffeine. By having a double blind study all biases for how the data should turn out were eliminated. In addition, the professors, the test subject, and the research group were unable to skew the data because they were unaware of when the subject got the
In our culture we seem to have the idea that if we pop the right pill, our dissatisfaction or discomfort will be assuaged. Lately, herbal drugs have become very popular as alternative medicines. They are purported to heal everything from memory problems to sexual dysfunction. One of the most common and most controversial herbal remedies is St. John’s Wort. As a cheap over-the-counter antidepressant, and with over 17% of the population experiencing depression sometime in their lifetime, its allure to the lay person is not surprising (Kessler, R. C. et al., 1994). Is St. John’s Wort an effective treatment for depression as many claim it is? Is it really safe?

For many centuries, humanity has been on an eternal quest for cures and treatments for many chronic conditions. At the present time, conventional medicine is mostly performed by doctors and other health care professionals, with the extensive use of pharmaceutical drugs, surgery or radiation treatments for disease treatment. Conversely, even though not as popular, complementary and alternative medicine and treatment options are slowly gaining popularity and becoming an addition to traditional medicine.
In the past decades the incidence of heart disease has increased, about three million people dying of cardiovascular disease in China per year (according to statistics from the Ministry of Public Health of China), which draws people’s great concern to find ways to take precautions. With the development of element analytical method, some types of chemical substances that are beneficial to cardiac health have been found. Lycopene is a very popular natural anti-oxidants found in recent years (Dai, 2011), as well as capsaicin and dietary fiber. Whilst some research focuses on the mechanism of action, little attention has been paid to usability issues, in particular to the generalization of health-giving chemical substances in ordinary meals. There is a lot of evidence that vegetables can positively contribute to prevent heart diseases, by supplying biologically active components. This article continues previous research in the field of Biochemistry and Medical Science, mainly trying to study the effective components which can prevent heart disease in edible vegetables.
Random and systematic errors are both factors that can affect the reliability and accuracy of the results respectively. As all the graphs contained outliers, and hence, scatter, this indicates that random errors were present. Such errors may result from the inconsistent masses of the Alka Seltzer tablets. As these tablets were cut manually with a knife, it is unlikely that the mass of each half of an Alka Seltzer tablet would be the same. Thus, when using the tablets to react with HCl, the true number of tablets reacting would have not been the same as the number denoted for the trial, and with each repeated trial for the same number of tablets reacting, the reacting mass and ratio would have not been inconsistent. Consequently, the

An effort has been made to do a comparative study on two tea selling companies so as to practically comprehend the consumer perceptions and choice of consumers on the two brands. A survey is done by providing with a questionnaire to a group of people of various ages who consumes tea.
Herbal remedies’ qualities are widespread availability, lower cost, effective for chronic conditions. Herbal remedies are the use of plants or plant extract to treat a person’ overall health. Herbal treatments are prominent for developing countries for instance, “in Africa up to 90% and in India 70% of the population depend on traditional medicine to help meet their health care needs” (Wachtel-Galor & Benzie, 2011), due to their low cost and availability. Herbal remedies have gained attention in the past decades, and expanding their uses due to the increased interest of natural therapies (Wachtel-Galor & Benzie, 2011). Herbs used on the remedies grow in the wild throughout the world, therefore making it easy to
Health claims are booming in today’s world. Many of these consumers are being misled by advertising and believe that their choice will benefit their health. Although herbal medicines have been in existence throughout human evolution, I have chosen to take a deeper look into these health practices. I’m curious if this is just another health claim or if there are actual benefits to taking these medicines.
